Register driver on tee bus. module tee registers bus, and module optee calls optee_enumerate_devices() to scan all devices on the bus. This TA can be Early TA's ( can be compiled into optee-os). In that case it will be on optee bus before linux booting. Also optee-suplicant application is needed to be loaded between optee module and ftpm module to to maintain functionality for ftpm driver.
Please use proper casing in the commit message e.g. tee to TEE and so forth.
Ok. Will do in v2.
What is TA?
TA there is Trusted Application. I.e. application which runs in a secure world (arm trust zone.). This also fixes the Microsoft ftpm driver which has a corresponding application for secure world.
